Feathers Lines is a Marking that places a feather line on the back of the waja in conjunction with the Feathers marking. This is an exclusive marking that cannot be currently created by any means, and is only obtained as generation 2 or higher via Estuko's cave or through breeding. Estuko is currently the only user who owns the feathers lines marking on a custom generation 1 waja.
All examples feature wajas with the marking in FF0000 (pure red). However, this marking can come in any Hex Color as well as rainbow (simply put the word "RAINBOW" in the hex field) and chrome (simply put the word "chrome" in the hex field).
