Lifebane

Curse that a Wood elf can have that causes the grass beneath their feet to wither away.
  Wherever the afflicted wood elf treads, green shoots blacken and wilt, leaves curling into brittle husks beneath their feet. Flowers wither in mid-bloom, and even hardy shrubs recede from their path. Survivors speak of gardens turning to dust overnight, of forests recoiling as if in fear. Though their touch could once have nurtured life, a Lifebane’s presence now drains the land, leaving a hollow echo of the vitality that once clung to the soil.
