I appreciate everybody trying to tell be to get information about the clan, thanks, but I have worked for White Wolf as Narrator, so I already got about everything for the World of Darkness (including clanbook tremere, second and revised edition). So yes, i know about the Dark Ages, and how the clan got there, etc. But I still don't like the clan, I'm maybe too much of an individual to accept their "sectarian" way of life. I prefer Malkavians (but that's what I get for dating a psychologist)
However I do love the clan Tremere as it is explained on my LARP session, our Regent is having a middle age crisis and uses thaumaturgy to play WoW with a mage friend of his while asking people to bring him a glass of water (the mage managed to make him "fake real blood" in pills, that only needs water to be drank), I got embraced just to fuck up the malkavian plans and we are going on alliance with the Brujah (the primogen is our pal and we like to giggle together, the three of us). Before you scream heresy, the backround written to be used as a base for this LARP is totally credible and realistic, it's just that the guy playing my sire/the Regent has a doctorate in psychology... And the character totally works !
So to coming back to the idea of kicking the gargoyle back to home, yes indeed there is much hate, but gargoyles do lose their willpower because of how there were created (experimentation with Nosferatu, Gangrel and Tzimisce if my memory is correct). The idea of a free Gargoyle is possible, as much as it is possible for a dead vampire to become a wraith, but it's very very rare (as much of a mage or a werewolf surviving the embrace ; in all WoD books, there may be about two cases of each ; the Tremere Wraith in Atlanta and Samuel Haight are a couple of examples).
If I remember correctly, gargoyles get maluses for when it gets dominated.. Usually, when the clan has a gargoyle, it is so much victim of dominate that he doesn't even have the wits to understand it's being dominated... so, to develop hate, that's one big step. I'd bet with a acceptable generation and a good persuation skill, it may be possible to trick this Gargoyle into going home at the Chantry.
But I am aware that if you choses the dialog options without any orders you can get it to join Isaac.
(Oh by the way, i apologize if some sentences do not make any sence, English is my third language)
