Doctor arrives at Terileptil base
The Terileptils' Soliton Gas Harvester, their critical resource for energy extraction and plague development, is abruptly abandoned when the Leader commands its removal. The sophisticated machine, central to their entire operation, is wheeled away by its operators to prevent discovery after the TARDIS materialization exposed their location.
Before:
Functioning at full capacity with the Terileptils greedily inhaling soliton gas directly from its outlets. Positioned prominently in their base as their primary energy source.
After:
Forthwith removed from the primary area as its operators hastily wheel it away under direct command. No longer harvesting gas, deprived of its operators, making it effectively non-functional in this location.
