Bank (Gambit)
From Destinypedia, the Destiny wiki
Banks are devices invented by the Drifter to store Motes of Dark. They figure prominently in Gambit and Gambit Prime, where the objective is to collect Motes from slain enemies and stockpile them in a bank. When a sufficient number of Motes are deposited at once, a bank can be used to summon Taken; filling a bank completely allows it to summon a Primeval.
