PoxNora is an online "collectible, turn-based, tactical fantasy game in which players command armies of fantastic creatures, cast spells of devastating power, and summon artifacts of ancient renown in order to defeat their opponents." These things are represented by runes, all of which should be easily found using this database. I put this together for personal use, but if it can help out the community of PoxNora players, all the better.
Coming soon: searching, sorting, color coding, and deck building.
