If this is the new Horde, can we have the old one back please.
Heads, hearts and other gooey bits look fine skewered on your steel plated Keep, plants (unless poisonous) are a definite no no. It’s time to hang the Interior Designer from one of those currently empty pointy bits.
Bonfires on the other hand are good. They could be better if you were at least burning someone in effigy (Varian for example) or just plain burning someone but at least they seem a bit more in keeping with the building. Why go to the hassle of making something which looks aggressive, bad tempered and quite frankly dangerous and then spoil the whole effect with flowers.
