An unnamed twoll practicing what appears to be very elementary Mathamancy.^Erf-b1-p010

Proposed Canon

A Twoll is a humanoid unit. Twolls share the same articulation problem as dwagons, gobwins, and spidews.

One notable twoll is Bogroll.

Twolls appear to come in one eyed (like Bogroll) and two eyed (unnamed twoll, as depicted) varieties.

Speculation

Apparently personal hygiene is a weak point of twolls.^Erf-b1-p037

Fabrication appears to be a Natural Ability of all Twolls. Other possibility is that Fabrication is an ability of Henchmen/Lackeys.

Bogroll created a breastplate for Parson. ^{Erf-b1-p036-p4 Erf-b1-p037-p3} Indeed, it seems that equipping others (just Warlords or others also?) is part of his job as henchman.^Erf-b1-p037 Later, Zhopa created a picnic basket out of an ordinary basket for Parson, and he implied that he could create more than that (e.g. chairs).[1]

Bogroll also cooked^{Erf-b1-p037-p8} and created a Parson-disguise that included a wig and a second eye.^{Erf-b1-p074-p11} It's unclear whether these are examples of Fabrication.

So far the only side seen using twolls is Gobwin Knob.^Erf-b1-p077a
