Having just recently finished the first full read through, the setting and tone of Songs for the Dusk is absolutely enrapturing. The departure from heavy grit and seemingly insurmountable odds to something that is intentionally challenging but meant to grow is a refreshing change for Forged in the Dark games. Particularly the dedication to crafting systems, prevalence of magic that is ubiquitous but difficult, and the introduction of the Harmony system (with focus to teamwork) makes the mechanics fresh.
But it is the setting that has caught me the most. I, personally, tend to bounce off the settings presented with Forged in the Dark games, but Tamaris is full of potential. The level of detail behind factions is just perfect enough to give a place to start, thanks especially to the Situation and Clock sections of the faction detailing. Capturing the feeling of a seeming post-utopia that has changed the world but only exists as myth is difficult but done well here.
I eagerly await any further updates and look forward to getting to play some Songs for the Dusk!
