Guild Wars 2

The name of the Exotic Axe, “Titans’ Vengance”, is misspelled.
It is actually spelled “Vengeance”. The ‘e’ is missing.
It is also [Titan’s], not [Titans’], because it is singular possessive, not plural possessive.

The axe is the Vengeance of a Titan or someone named Titan; Titan’s Vengeance.
Unless it is referring to The Titans, as a group, and the axe is the vengeance of the group of The Titans. Then it would, indeed, be Titans’ Vengeance, though it’d be better to include “The” before it; The Titans’ Vengeance.

Just curious if it is a single Titan, or a group of Titans whose Vengeance is this axe.

Totally with you on the vengeance bit but the titans were indeed a thing in GW1. You can read up on them on the wiki and decide for yourself if this weapon is referring to a specific titan or the group as a whole. http://wiki.guildwars.com/wiki/Titan

Look on the bright side – at least the text is not Korean/Chinese like some items
