A few weeks ago I started my first 4E campaign as a DM:
Shards of Light, Shards of Shadow. Its set in Eberron and I'm using the wonderful
Obsidian Portal as our wiki.
We had our fourth session last night (I haven't put this up on the addy log yet). So far, 4E is a blast to DM for and with the
DDI Compendium a breeze to create encounters for. Still working a bit on the encounter balance (most encounters probably have been a bit on the easy side), but otherwise I think it is going well. Players seem to be having a blast.
Looking forward to the drop of the
Eberron Player's Guide next month.
