Personality
Calculating | Skillful | Intelligent | Caring | Elusive

The first thing to note about this relatively elusive she cat is that she's extremely calculating and precise with everything that she does and if Riverclan had a special forces team of warriors, Cobaltshade would surely be on that team, perhaps even head of it. She doesn't attack with strength, she attacks with precision and speed and well thought out plans and tactics and enjoys outsmarting her opponents more than anything.
But that isn't all this Russian Blue is, in fact, when it comes to her family, she's exactly the opposite, she's incredibly friendly and loving as well as caring, making sure to be exceptionally gentle around kits and even more so her own and that cold, calculating exterior of hers is pried away to reveal that loving heart of hers. She does everything in her power to keep her loved ones safe and happy at all times, but due to her being such a calculating cat, she's rather awkward when it comes to feelings. She doesn't know how to comfort other cats or even express her own feelings to others. She's perfectly fine when it comes to taking down others in an assassin like style, but when it comes to how she feels about things? She's like fish out of water. 
Nonetheless, she's a good she-cat once you get to know her, you just have to look past her calculating and relatively cold exterior, if you look past that? She's a wonderful friend to have and an amazing ally. Trust me, you do not want to be faced against her in battle.
