>Why was ADIDO so important that a deal was made for her and she was passed onto three different mothers?
canon: she was a bargain chip from the pale king. herrah promised him to be a dreamer to seal the hollow knight and to try and quell tensions between hallownest and deepnest and bring their kingdoms together if the pale king gave her a divine child.

non-canon speculation: deepnest's relations with the pale king's civilization were very tumultuous so hornet was likely not received well by deepnest's citizens, hence why she was sent off to the hive to train under vespa and why she was named hornet. her original character concept was "daughter of three queens" (white lady, herrah, vespa) but it's not clear if this is what the actual lore is since there's nothing in game that states this outright.
