Yes, i held an event
It was about 2 letters. They were hid in a mailbox in Tanarthia and at two statues in Hotaru. The letters said about a spirit that would give something to his two friends. The ones that found the spirit had to convince him... One lied saying he was the son of the friend, the other convinced the spirit he didn't stole it.
The winners were:
Hideko Toyama who won a Naginata of Ogma
and
Laewan Lborev who won a Speed+1 ring
