Oniverse Board Game Lot 2 Games: Castellion and Sylvion w/ Below Ground Promo

Used a couple of times but I found I'm not much into solo games. All games are complete in box. Please see pictures for more details.

Castellion:

Castellion is a tile-laying game in which you form parts of the castle for defense against monsters. Each turn you flip over a tile and either use its special ability or place it as part of your castle. The more towers and keeps you form, the better your defense against attacks. Ranks prevent traitorous tiles from affecting you fully. When all three monsters have attacked and you still have a base of six tiles, you win.

Sylvion:

The terrifying Ravage and his Fire Elementals want to burn the grand forest of the Oniverse to dust. Only you can face the heroic task of stopping this unspeakable offense. Build the best Defender deck by skillfully selecting cards from those available.

Sylvion: Below Ground is a 16-card expansion that adds an additional challenge to Sylvion.
