Unfortunately Holden, what you do now very difficult. You wait! wait for the gm to post some new Advs, (he's posting them fairly quickly these days so it shouldn't be a long wait), and grind up any skills and powers you want to increase.
Unfortunately there isn't yet a way in the main game to learn thievery or unarmed combat, hopefully when the Gm posts the new map system and new locations he should also give us the oppertunities to learn some more skills and powers (My charactor really could do with learning diplomacy skill).
Btw Holden, have you ever considdered registering on the Sryth.com forum, it's a very friendly board, and a good place to discuss Sryth, and other randomness.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
