"Why should I be disappointed!" the Undead retorted.
"Could it be a hidden reward?" Someone speculated wildly.
No one thought that adopting a cat was a result of an imperfect quest system; they simply believed that they had accidentally achieved some feat and thus earned a reward.
The mount system had been open for a while, but it was a small-scale test. The Calamity Warhorse couldn't keep up with the Undead's advancement, ultimately becoming a beast of burden for hauling goods.
The pet system, however, remained closed, so this sudden provision of a companion really hit home for most people.
