Slight correction, Echidna is still "alive" she is currently known as, Omega in Gusteko (just north of Lugunica)

Rewind 400 years, she created Sanctuary with assistance from Ryuuzu. The purpose of the sanctuary was for her to perform experiments to transfer her soul into a compatible vessel(s) as a way to preserve her knowledge and magic (basically immortality on the cheap.) Unfortuantely for her, the experiments failed to yield a vessel capable of withstanding her knowlege and magic simultaneously. Echidna then chose to absorb Ryuuzu's spirit into her own and using the techniqies she had learned through experimentation, she transferred herself into Ryuuzu's body and was renamed, "Omega." Fast forward to present day, Echidna's soul that contains all of her magical affinities is what remains inside sanctuary.

Roswaal purposely manipulated Subaru by using Emilia as bait. Once Emilia was inside the sanctuary he knew she would not be able to leave without lifting the barrier (or her soul would be trapped because she's a half-blood.) Roswaal took advantage of Subaru's "gift" and his devotion to Emilia and manipulated the circumstances knowing that once the barrier was lifted, Echidna's remaining trapped soul would be freed.

Once the barrier is lifted, there's nothing preventing Omega from reclaiming her lost/soul magic that it contains (effectively completing, The Witch of Greed.)
