Have seen him here in Norrhart Domains during a vanquish.
Remember him popping up whilst killing Baglorag Grumblesnort and I got his green hammer instead of Jormungand's 
Used to run Darkrime lots and regularly ran though Bjora Marches.
Have seen him here, on the corner by a tree.
Also seen him several times in the most northen point on your map.
Found a couple examples from eotn, maybe this confirms or eliminates something?
2 50's, 1 point and a scroll
Gold Scroll and a leet tome
Also think you missed Dyes from your list of possible drops?
Earth scroll 250e
Zchest like dungeon chests can drop naked staffs, not common but does happen. Recently got some doing zrank myself.
