Dawn's white earth stallion Harbinger general from this vector by Vector-Brony.

I autonomously named him Silver Stream; ironically, this was back in 2016, before the canon Silverstream appeared on MLP.😁

SVG for reuse.🙂

MY 100TH ARTIST UPLOAD! WHOO-HOOOOOO!🥳😄

Edit 1/6/2020: Could possibly be Steelrain based on this, but I'll keep my fan name for him as well.

Edit #2, 1/20/2021: Identity as Steelrain confirmed.

I'll still personally keep his other fan name attached as a secondary, though…maybe like Steelrain Silverstream?😀
