From the introduction:
A One-Round d20 LIVING ARCANIS INVISIBLE KINGS Adventure
Lustia Adventure 2, Campaign Year 5 (Lampyris, 1029 I.C.)
As a new spring falls upon the nation of Milandir, the first flowers push out through winter’s thawing veil, offering their fragrance to the insects and birds that are waking from their long sleep. The frozen ground yields to sown seed, winter’s hoarded goods are readied for market and the powerful and wealthy drink in fresh news and consider their plans anew. Everywhere, the promise of another year’s profits stir people from their winter rest to act. Perhaps you should do the same, lest last year's prosperity fall into this season's ruin.
