Okay, I have concept art for Lapis' sister Onyx.:

Onyx is a helpful character in the series. She is Lapis' sister, and helps the player by explaining gameplay mechanics and aspects. This help comes in the form of communication crystals; jewels that are identical to Onyx's gem and project her image and voice, communicating with the player. You can even pull up a menu of communication crystals and listen to their information if you ever forget anything. She's kinda like the Coco to Lapis' Crash Bandicoot.

She's also kinda snarky and sarcastic when she's not helping you (which is why she looks kinda gothic).
