Is this for the Magincia rubble quest? in which case the answer is the npc at magincia gate, or the quest to convert cloaks of corruption, in which case I can't remember which is which, but one seer is outside Yew Abbey, one is in Serpents hold and the third is just outside Moonglow Lyceum - unless they went away with the ending of the event.
doh! beaten by Frarc, who knows and is less verbose.
