House Ecale is a Rogue Trader house. In 601 390.M38 House Ecale, under the leadership of the legendary Sia'hadn Ecale, formed a pact with the Marines Errant Space Marine Chapter. Although the details of this covenant are not known by outsiders, it is known that the entire Chapter accompanied Ecale's already substantial army on a forty year expedition into the Ghoul Stars. Ever since then House Ecale's expeditions have included small contingents from the Marines Errant. Those Astartes who return do so bearing the Ecales' sigil on their Power Armour.
