you start the tribunal quests in mournhold and you get to mournhold from ebonheart you need to speak with asciene rane about "transport to mournhold", then in mournhold you need to go find the temple and i think the first person you need to talk to is fedris hler (in th etemple reception area), and then you should be put on a series of missions which will eventually lead to you aquaring truflame...does that awnser your question? if not feel free to elaberate
Might I ask where can I find this person to Mournhold? As in which building like Mages guild building, fighters guild building etc
