Desiree had not initially been too comfortable with her role in Kalysto’s plan. In fact, the first few nights were nearly horrific because of the ways that Desiree messed up in performing. However, she wanted Kalysto to be happy. So, she had stubbornly stuck to it and performed each night in hopes of giving her mate what was desired.
However, as time went on, Desiree noticed how troubled Kalysto was. So, she gave the elf a few books on supposed theories on how to improve the chances of becoming pregnant. Some of the advice was rather absurd, such as hand-standing for an hour after waking up. However, Desiree just gave her the books anyway.
