Richard Garriott's Portalarium may have successfully kickstarted its Shroud of the Avatar project back in April, but that doesn't mean the team is done with the rewards.
In last night's dev update, Executive Producer Dallas Snell introduced the Dungeon Kit: a Unity-based content creation tool that is now available to all Developer-Level ($400+ pledge tier) backers. This tool not only lets you build assets for SotA, but it also allows you to build assets for any Unity-based game that you may be working on. Snell reports that this may be the first time that something like this has been made available to other game devs or publishers before the game is even released.
Be sure to check out the full update for much more on getting started with the kit, getting started with Unity, and some interesting factoids on how surveyed devs will be using the Dungeon Kit.
