Like playing Eberron? Like Siberys dragonmarks? Butt-hurt that they didnt include them in Eberron Campaign Setting or Eberron Player's Guide? Then this article's gotcha covered. The first two pages provide iconic character combinations that fit a given dragonmark, such as human fighters for the mark of Sentinel, as well as some brief advice on fucking with Multiclass feats so that the benefits provided better fit the dragonmark you have.
Do they fit what the Siberys marks did in 3rd Edition? Fuck no. The Siberys Mark of Passage doesn't let you teleport hundreds of miles once per day, instead allowing you to teleport 20 squares, bringing along willing allies, and you don't have to see where you're going. Siberys mark of handling is also pretty cool, giving you an extra action to have a companion, summon, or mount make an attack with.
Ultimately, if you enjoy Eberron this is going to be something that at least one player is going to pick up...assuming anyone actually gets to epic tier. >_>
