Speaking to Grey is the easiest first step as talking to either of the other two would require a trip out of the camp and a journey of some days to reach where they are or in Tepet Agram where they may be as he has been seen in several locations by hunters and seems not to want to stay too much in one place.
What Grey says when Bob questions him.
The The Bulls main camp is beloved to be several weeks to the north and west of the Moose peoples camp on the edge of some sort of large body of water a lake or perhaps a sea, Grey is not sure as he has never been that far north and the hunters and gatherers of the moose people consider the place to be ill omened for some reason, but he has learned to respect the Moose peoples taboos as those he has investigated are there for good reason. The Bull seems to have a large number of ghosts with him, how many none of the locals are sure as they are mostly beyond the hunting ranges of the local clans. Large bodies of several hundred have been spotted apparently patrolling on and into the edges of the locals hunting range. The locals are frightened by these and avoid contact even if the ghosts seem to be form their own people and from reports whilst they are some sort of northerner many are foreigners as far as the local ghosts are concerned.
Grey is not aware exactly how the Bull was defeated but there are rumours gathered form tribes nearer the area speak of a second great battle to the south east of his camp between his horde and more troops form the realm which though the realm force was much smaller went no where near as well as the first.
Grey has an idea of something that can be used against him and his army a first age weapon which he believes has not fallen into the hands of any one else. he does not have details but its some sort of bomb which shreds souls
Grey Has had several reports of Tepet and met him once, Grey is not sure what he wants beyond immediate survival in the underworld but he is defiantly looking for the ghosts of his fellows and Grey suspects a measure of revenge. Grey believes that The Bull is either unaware of the Tepet or unconcerned by him.
Grey has not discussed alliances with Tepet or any one else but thinks both he and Logir will cover each others backs despite their differences.
OOC to lean more of what if anything Grey might not be telling Bob roll Perception + Socialise, I could also do with an e-mail address to send Bobs character sheet to please PM me one. Ginger
