It is my chance ! (Patreon)

Lua was walking alone carelessly in the forest, when she was attacked and captured by bandits. Or maybe they are slave traders, she can't really tell. They brought her to their camp, ripped her clothes, took her weapons and left her tied up in a tent. She can hear them outside, planning their next evil projects.
No time to waste ! Lua's in danger ! She quickly thinks of a way the untie herself and escape from her ... wait ... what ?
