Echoes of Time

No — cards on the Time board are not considered part of your Fellowship and you cannot use their effects or icons until they are summoned into your Fellowship (played directly to position 0 are summoned immediately). (page 5)

At the start of the round’s Time phase everyone simultaneously inserts the off‑board Time tile on the left, pushing tiles right; any cards on the tile that leaves the board are summoned into your Fellowship, and if two leave you choose the order to summon them. Immediate effects from summoned cards (and permanent effects that trigger) are resolved now. (page 4)

Each Time tile can hold a maximum of two cards; if the indicated tile already has two cards, place the card on the first available tile to the left that has fewer than two cards. (page 5)

No — conquering and fortifying are separate actions, so you cannot fortify a Source you have not previously conquered or fortify it in the same single action as conquering; to fortify you must meet the II strength requirement and perform the Fortify action. (pages 5–6)

When you place Creatures under a conquered Source (top visible), you cannot use their effects but their top‑icons (cost, faction, type, specialization, strength) remain active and they still count for end‑game VPs; when you fortify a Source you slide creatures completely beneath it and they no longer provide effects or icons, though they still count for scoring. (pages 5–6; moving creatures under a Source is also allowed as a free action but not if they have an Activation token). (pages 5–7)
