I got a full key this weekend(6/15) ,Here is a picture of the rock face. Examine : This rock has a hollow carving in which a triskelion-shaped key could fit. The rockface was South of the Releka Slayer cave entrance. Loot was : Elite clue, 5 uncut Dstone, 3 papaya, Plam, and calquat seeds. About 8 Hours to get the key frags. 5 hours pick pocketing a mix of elves and dwarf traders. In that time the elves gave me Frag 1. All the rest of the pickpocketing from Dwarfs was useless. The last 3 hours were done killing Dark beasts, they gave me the last 2 frags.
