Dar_Krusos, called Kru, led the guild Kangronomicon during the Ordo Malleus period. Everything known about him comes from Drew1011's retrospective account of 2018.

Spham handed Kangronomicon to Kru "mere hours" after the change of ownership at Holders of LE on 22 September 2015; Drew1011 described him as her most trusted chief^[1]. Shortly before Ordo Malleus was formed, Kru told Drew1011 that Holders of LE had to elect a council of four officers — a Diplomat, a War Commander, a Community Manager and a Merchant — without saying what for^[2]; the same four offices were then required of every member guild. Kangronomicon, "led by Kru", was one of the seven guilds at the alliance's founding on 6 November 2015^[3].

When a group of leaders wanted alliance business moved out of the chat run by Paladin A'renos, they took the request to Kru, and he approved the new chat^[4]. He then created a further chat named "Shadow Government", which he described as the highest leadership tier in the alliance, one step above the leader chat^[5], and it was Kru who agreed to admit Killerfish to it^[6].

When Drew1011 withdrew Holders of LE on 9 March 2016 — the departure that ended the alliance — his leaving message characterised what Ordo Malleus had become: "instead of this alliance being a balance between all the guilds, it become more of a dictatorship between Kru and Arenos". No other account of the alliance's final weeks was ever written.

Drew1011 wrote that Kru left Wynncraft soon afterwards and "to this day he has never returned, except to pass down leadership of Kangronomicon"^[7].
