I would like to see Lona riding a summoned Familiar, goblins have mounts, one day a personal pet would be good if there could be a market for beasts and magical creatures to sign contracts or space events in different regions, I don't see much use in cats or dog, even though they are very fast in attack, they lack defense and resistance, it would be really cool if there was a quest to capture magical creatures and tame them.
If I could give Lona a familiar animal, I would give her the most useful of all, a Unicorn and it could provide some advantages such as carrying her items, increasing her space and weight, decreasing her stamina consumption when walking, finding food like fruit or producing milk abilities (Magical Healing Shield, Magical Teleport, Magical Explosive Ball, Revive Lona and Allies 1 time per week) combine easily with the builds, and would be a great reference to Ihuarraquax from The Witcher franchise or Lurue, the unicorn goddess from the D&D game.
