Please, consider adding this:
1. an ability to construct (special) Porticos underground.
2. hearth magic (very high cost (like 30K EXP)) to "tie" 2 porticos within 1 village for the sake of creation of the stable two-way portal to move between two sites within 1 village. Each jump eats Travel Wearness (like roads) and the portal itself consumes Village authority like Natural wonder (10K per day) and cannot be deactivated/reactivated more than once a day.
why do we need it? moving from surface to l8-9 mines takes to much (not even time) loading screens making it not hard but annoying (which is definitely opposite to fun), so even if it would take same time (let it work with preparation hourglass (like docking knarr)) as moving by ladders, it would still be very nice to have.
