There isn’t an official Games Workshop model by that name in the current catalog. If you’d like a flavor-text blurb in GW style for a fan-made concept, here’s a short description:nnMalstrain Coalescence is a grotesque centerpiece, a living hive of corruption in which scores of Genestealers fuse into a single, pulsing gestalt. A central, sputtering core drives a tangle of sinewy limbs and gnashing mandibles, each tendril snaking to lash and bind the nearby cultists into one creeping mass. The air around it reeks of mutagen and hive-musc, turning devotion into a fevered chorus as more hosts are drawn into the coalescing filth. On the tabletop it marks the moment when faith and flesh fuse, a malignant focal point that twists the Malstrain Genestealers’ brood into a single, ravening entity. If you’d like a shorter or more evocative variant, I can tweak the tone.
