Trinsic Archery Butte

[Slayvite]

While looking for the last of Pete's clue's ive come across many old event items. However i'm not familier with this one.
Behind one of the Archery butte's is a quill with the word 'Esoteric' wrote on it? Any ideas?

May one of the Duchy of Trinsic can enlighten you
