Motes of Inspiration. The Chronicles of Nerezia, #5

Fate and friendship brought Horace, Rumi, Keza, and Aliyah together in Rumi's sentient self-propelling wagon. They seek the forest haunting Aliyah's dream, hoping for answers about the elf's past and unique abilities-but first, they need to traverse a world haunted by Fragments, dangerous shards that can possess travellers and react to Aliyah's presence. They've reached Virze, a marvel of art and engineering and a city in which all acts of creation are beloved.
A perfect occasion to explore and rest before the next leg of their journey. except that Rumi desperately wants to avoid his hometown and the demons of his past. When the Wagon crew realises half of those might be fears of his own making, however, they refuse to leave. But between the curse that ran him out of town and the source of his engineering skills, Rumi has been keeping even more secrets than they'd expected.
He'll need all their support to face the loved ones left behind and prove to all, himself first and foremost, what he is truly capable of.
