Grimwood resemble dead trees, but in fact are fierce creatures with a strong connection to the spirit world. They have taken it upon themselves to keep guard against grave robbers. Each Grimwood has formed a bond with a spirit bird and together they stand watch over the graveyards of New Transylvania. The ghostly birds soar high over head scouting the area for these fiends with pickaxes and shovels, then through a mental connection the birds inform the Grimwood. The Grimwood silently stand among the trees waiting to punish the grave robbers for the terrible actions.
