Adrian summoned Saena and told her to accompany Solstice since using her blood as projectiles drain her health. Solstice might be able to control blood, but it would take time to control the blood of other living beings.
It is inefficient for her to use just a blood sword which is why she also fashions her blood into arrows that strike at her target from afar. Adrian made sure that Saena sticks close to her so that she can immediately heal the health that his sister loses when creating weapons. As long as Saena is with her, Solstice can get healed and have increased health regeneration in the process.
Adrian summoned Sirius next as the Fenrir told him that he can walk on air. Adrian could not easily believe it until he saw it with his eyes. Sirius could literally walk on air as a result of his evolution. He has yet to fully explore all of Sirius abilities as he tends to focus more on their strengths rather than their miscellaneous abilities.
