Kozilek + Ulamog - Destructive Path

Each of them was staring in a different direction from their high vantage point in the mountains, taking in what had surely once been a striking vista—before the Eldrazi came. His own eyes swept across the ruin of Sea Gate and the desolate waste that spread out from it, and came to rest on the Eldrazi titans—two of them now. Ulamog, who had been trapped and at their mercy, and now Kozilek, whose sudden appearance had ruined everything.

The titans were creeping along, not quite side by side, leaving twin trails of destruction in their wake. But where Ulamog left the all-too-familiar bony dust behind him, Kozilek's trail was a bizarre swatch of gleaming stone formed in strange square spirals, coated in a sickly sheen of violets and greens. Of course, their spawn teemed around them as well, but Gideon saw no other signs of life.
