Turbine's official Dungeons & Dragons Online website has been updated with a new developer diary called "Trespassers!". It's actually a story rather than your usual developer diary, but still makes for a good read. Check it out:
My cohorts and I have begun to devise even better means of protecting our treasures and aiding our pets. The evil gnomish artificers report that they're installing new magic devices that will aid the pets as they patrol my domain and ward off trespassers. The problems we've had with our precious pets running blindly off of cliffs will soon be a thing of the past. I rejoice, for we've lost far too many of them that way. Stupid kobolds.
