From the Sonoma EM Events website:
Please feel free to join us for some treasure hunting fun. This is not an official EM event. Some people expressed that they might like to do a T hunt competition and we are going to do a few maps and see if we might like to do a shard competition later.
Meet at the Counselor hall at 1 PT 2 MT 3 CT 4 ET.
Again this is an activity for the shard to have fun T hunting.
