What exactly is this quest about? any short synopsis - all I see are credits.
Is it geared for good/evil/neutral characters (how good do you have to be)?
It is described as the start of something larger - does that mean that at the end there are tons of dangling loose ends that lead to nothing.
Not knowing these answers has kept me from even looking into this.
well a bit neutralish... it is basically Telvanni in the far eastern edge of Cyrodiil - and as anyone who has played MW knows the Telvanni aren't persay evil but they are a bit short on the morals department... I'd say it was fine for anyone really.
You do get to find out that Falanu Hlaalu (alchemist in Skingrad) is a total nutjob - especially in her taste for boyfriends.
there are loose ends but not too much IMO; you get to climb partway up the ranks of House Telvanni for one thing, but really I don't feel that you should be able to be grandmaster (or whatever) of every guild/house there is so that's fine with me... it'd be nice to have somenew quests continuing but not really essential IMO.
EDIT: as for timing I'd aggree with Lilith - makes more sense after the main quest but should work fine before (I only played it after so can't say for 100% certain). Also for player level... I played it last with hmm 26 IIRC; relatively (okay very) easy battles - but it's been a while.
