The first secret

You gotta have the patience and believe you're gonna make it
Gotta hold on

A strange sound from above made the little mare look up just as a glowing blue glob of something descended upon her. Shrieking in terror the little mare bolted and dashed a ways into the dense jungle, bucking and thrashing to get it off. What was it, why did it cling to her, would her skin burn and sizzle and be eaten away by some acid or would she fall down dead from whatever poison it might inject her with? But for all that she flapped the wings and kicked and rolled on the ground, the glowing mucus remained where it was, and to make matters worse it was beginning to harden.

Grimacing in disgust as the solid, blue mass began to solidify all along her back, she tried to flex the wings and found them hopelessly glued to her sides as tiny, painful downs were caught in the sticky mess. With every passing second it grew harder and harder, and Erthë was horrified to realize that it made walking or moving or even lowering her head towards the ground nearly impossible. Anger quickly replaced the initial panic, and with a snarl she tore her head around and gnashed her teeth at the luminous crust, ignoring everything Badger had once taught her about ingesting unknown substances...

It was useless. She was stuck, or rather it was stuck to her and it didn't even matter because it was awful and bothersome... and to make matters even worse she felt how the damp, soaked skin beneath the substance begin to itch.

"Why?" she moaned, turning her eyes to the sky as if to beseech some god for answers. "Why me? What have I ever done to deserve this!?"

Erthë waited, but to no surprise, all that responded to her was a deep, empty silence, before the hidden creatures of the rainforest resumed their squawking and buzzing.

I know you're tired of surviving but you gotta keep on trying
Hold on!
