Magna of Illusion

Cornwall and the harbor
 Where witches went mad more than once and
 Until this day
 In dreams at least
 The lighthouse at Lost Christabel
 Squat and hugely tilts
 Upon the strand where Grandad's house was built
 And having stood the test of time
 The starry gale the bloody tide
 Grandad's house though gaped with hooks
 And filled with books
 Could stand no more until
 A certain prophecy
 Once read - now stood
 Before the world fulfilled
 ♪
 Now of these books in Grandad's keep
 Some of them were new but mostly they were old
 And the oldest was a scroll
 A prophecy that read
 When the riddle begins
 The story will end
 August the First 1892
 And in the guise of destiny
 Grandad quit Cornwall
 "I'm a captain of a ship
 My ship is charmed, and called Plutonia."
 Stories on land, storms at sea
 'Tween 1892 and '93
 When Grandad sailed for Mexico
 ♪
 Ships charmed and ordinary
 Sailed the glidepath to the sun
 And when the sun proved false
 As it always does
 Some of them would be lost
 And some would sail back home
 It was no star
 But a magna of illusion
 I mean by that
 The mirror found
 In the chamber of jade grown like a seed
 Deep within the ground
 The mirror found
 By one man
 So on and off again
 He sailed the Europe's rim
 On and off, off and on
 Until his time had come
 ♪
 Through tears and smiles
 The last domain
 The rods of broken crystal
 On and off, and off again
 Until his time had come
 Late to the story that had been
 But early to the riddle not yet begun
 August the First 1893
 The charmed ship Plutonia
 Sailed like a ray into Cornwall
 And none too soon it seems
 That night the Captain's granddaughter
 Would celebrate her birthday
 "I've come a long way," said the Captain
 "From Lost Christabel this night
 Accompanied by my dog familiar
 To blast your rafters with my surprise!
 Granddaughter, it's a foreign mirror
 Taken from the jungle by crime!"
 Stories on land, storms at sea
 'Tween 1892 and '93
 When Grandad sailed for Mexico
 When tables collapse
 And floors have filled
 And the party's over, it's all over
 Sea-dogs and rockers will dwell on doom
 I've warped the stuff of ground
 What seems to be is not
 Behind closed eyes
 Realize your sight
 Mine, granddaughter, proves a surprise
 More light than sun
 More dark than night then
 More a snare than lust
