>They directly say the idea is to recombine multiple arathim into a bigger form but the tendons and shit weren't strong enough for the heavier body which is where the gruenaks come in. Skektek litterally introduces the garthim as a combination of arathim and gruenak.Skektek speculates it could be "grafted" into a larger form; he could easily be speaking about a genetic graft. When he's speaking about the substance of the flesh being insufficient, he specifically mentions fibroblasts, which are the cells responsible for connective tissue. Sure as hell sounds to me like he's talking genetic hybrids.
Either way it's very different from how the original lore treated Garthim; it described them as being physicalised dream-constructs that were entirely magical, hence the way they fell apart into empty shells when de-powered.
