I do not understand why everyone is set against them settling in Kolanse.Tavore's duty to the world is over now that the CG is away,it's time for her and the BH to have something back and since they are outlawed by the empire and there is a country with a free throne thanks to them it makes sense for them to stop there.
1)Returning to the empire is highly unlikely with Rel as emperor.While he might be pragmatic enough to accept the Host it would make no sense for them to give him more power.He is still an evil scheming bastard and in ICE works we see that
2)Fighting against Rel is highly probable but i see it more as something to do in the future than an immediate aftermath to the events in tCG.The bonehunters have burned most of their ships and even with the Host they are only 2 armies against what Rel has managed to recruit after the events of RotCG.They need time to rebuild,a fleet and a reason to fight versus helping to free a country in need of help that is right there where they are.
Still a sudden attack on the empire is not to be discounted.
3)Joining Lether is an option but for Tavore and the BH the story is just beginning and they need to be independent to do it.
4)Ruling Kolanse seems the most likely thing to happen for several reasons:
-The Letherii rulers and the queen Fireheart are their close allies.
-Tavore was always ambitious,we know that from from GotM,long before her mission to save the world and now she is free to pursue her ambitions.There is also the prophetic "She will be queen"
i think from Silchas Ruin that many think related to Sandalath,but she already had her own prediction in the reading in Letheras as Queen of HHDark so Silchas words would be redundant.Also SE loves to hide as many things in a single phrase or event as he can.
-Ganoes is MotD,he has no need for an army(and he makes a really poor commander in a strictly military sense,his victories are due to his powers of Master ,the synergy between him,Quick and the others and the fact that the sappers acted against his direct orders regarding the munitions).Paran's Host is better employed under Tavore Paran.Also the Host and the BH need a place to stay and recover after the long period of fighting and they really would be wasted as mercenaries.
-the Kolansi people have just been freed from 30 tor more years of brutal oppression,mind control and persecutions.They were ruled by the FA,a race extremely minimalistic,pragmatic and mysantropic that had absolutely no interest in the humans other that as slaves.It is hinted that most books were burned,that the mind-controlled soldiers were forced to hunt their own people and that there was no contact or trade with the outside for many years.
Try and imagine life for the civilian population used to support the army:years of brutal labor with no place for expression,fun,creativity or free thinking;no other productions in the nation other than food,clothing,blacksmithing and other supplies.
The soldiers probably fared much worse;repetitive training for years at best,innocent blood on their hands at worst all under mind control.
Think of Sorry in GotM right after the possession ended,she had to be healed as probably many of the Kolansi will have to and what is the best tool to heal the mind? Mocka,a warren in the continent where the only magery known to most is that of holds and from the conversation between Seren Pedac and the CG mage(forgot the name)it was hinted that power over the human mind is a rare if not absent thing in Lether.
Even without mind damage the FA stayed for enough time to screw up generations of people.Many will probably not remember what money is,how to read nor will have the commons sense needed to live in a normal society and who are they neighbours? Greedy Letheri and Bolkando ready to exploit the ignorant.
To the point,Kolanse needs someone strong to protect it from outside armies and clashing cultures and someone caring and compassionate to heal the population and the Parans have both these qualities.
On the positive side Kolanse is as close as we will ever get to a "blank state" nation,something that can be shaped by its rulers and who would be better than the main characters?
-I think of Kolanse as a new starting point for a new empire,a MalazV2.Let's compare old guard and new guard,there are parallels.
Empire's Old Guard:Kellanved(crazy mage),Dancer(assassin),Tayschrenn(fire mage-priest of D'rek),Dassem Ultor/Dessembrae(god-touched soldier very hard to kill) and the more normal people like Dujek Onearm and the others.
Tavore's New Guard:Quick Ben(crazy mage),Kalam(assassin),Deadsmell(ice mage-priest of Hood),Ruthan Gudd/Rynthan(god-touched soldier very hard to kill) and the more normal people like Rythe Bude and the others.
I left Surly out of the list as her parallel is a bit harder to guess;she was mostly dedicated to the internal affairs,spying and covert operations inside the empire until Kel and Dancer started to be more and more absent.
Tavore's right hand is Lostara Yil but the character that parallels Surly the most is actually Ganoes:he displayed a penchant for investigation at the Itko Kan massacre and worked under cover as Adjunct Lorn's aide for 2 years,becoming the only one with such background(other than Kalam but he is more of a fighter than a subtle guy,he is Claw trained but acts more like a Talon),his powers as MotD allows him some sort of scrying,deck prophecy and the power to bypass walls,all usefull for a spy,the link with the hound makes him deadly even with his bare hands and maybe some heightened sensitivity(or that is thank to the MotD powers,like spotting Blend and sensing health from the girl in G'danisban).There is also the symbolism between a hound and investigation.
Also Ganoes would fit in a more positive light with 2 themes associated with Surly:
"Thronemaster"(the meaning of the name Laseen) as the one who gives Tavore the means to free Kolanse and get the throne and as the soft power that takes care of the nation.
"Betrayer"since as the MotD he has to put the interests of the world above Kolanse and will have to leave the nation to fulfill his duties,once the situation gets better.
As for Lostara Yil she can probably stay at Tavore's side but i have my Crazy theories about her fate
So these are my reasons for the malazans to stay in Kolanse,what do u think?
"My Queen, neither mortal nor immortal can fathom the mind of an artist. But as a general rule, between two possible answers, choose the more sordid one."
