This "container" is a static item within Temple of Droga. It looks like a pottery wheel and is "operated" like any other static tradeskill container (forge, kiln, pottery wheel, loom, brew barrel): by left-clicking on it. It's location is N200, P1115, N250 inside a locked jail cell (the cell door can be opened with a Droga Jail Key which drops off of either a goblin prison warden or a goblin janitor within Temple of Droga.
This is the "Stupendous Contraption" referred to by an enslaved iksar within the goblin caves in Frontier Mountains. It is part of the Crusader's Test of the Lord, which is one of the (several) quests in the line of quests to receive the Greenmist. Many players consider the Greenmist to be effectively the Epic 1.0 for Iksar Shadowknights, due to the difficulty (impossibility?) for Iksars to be able to attain high enough faction to do the actual Shadowknight Epic 1.0 quest.
-- Troggdor, 50 Iksar Shadowknight of Quellious
