Thanks for your message; glad you liked it overall! Yeah I definitely wished I could have put more secrets in, but I'm still relatively new to stories so I just managed to slap a two scripture verses in.
Really not sure when or if I'll get back to it but I was thinking of having it open up to outer space and / or having a ying yang with two trees. But it's all up in the air, so really anything could have gone! If you happen to think of cool stuff I could have put down there let me know, haha
