any place to buy/trade for runes?

[loreangelicus]

I know I'm getting ahead of myself here, but I'm thinking of putting my paladin game on hold and trying a warrior. I have a phenomenal start with the paladin game, first 4 islands and I have 4 Ancient Knowledge scroll, 2 Call of Death, Eviln, Gladiator Sword and Ancient Amulet at Debir, Black Helmet somewhere, guaranteed Call of Colossus at Scarlet, Magic Spring. Overall a very good game save. But what had me thinking to just start a warrior game were two things:

1) I just found out from forum posts that the ultimate ability of the paladin DOES NOT support my no-loss game. And I thought this was supposed to balance out the lack of Resurrection scroll like the paladin had in KBTL.

2) I also read somewhere that there is a place to buy/trade for runes, making the already powerful warrior even more powerful; the only reason I didn't take the warrior at the start was because I wanted a lot of skills from ALL three skill trees. But if there was a place to buy/trade for runes...

The warrior also has a more useful ultimate in keeping rage between island hops, and generating more rage. More leadership is also great.

Could someone please tell me in what island you could buy/trade for runes, and what the exact mechanics for it are (how gold much per rune if buying, and the conversion cost if trading)?

Much thanks in advance.
