Excerpt from Esoteric
Pilgrimage Destinations of the Gothic Sector, Volume 7, by Adept Matthias
Laetorius.
"The Harrow'e'en celebration on Ophatran Secundus coincides with the
yearly arrival of the Emperor's Tithe Fleet. The people of Ophatran believe
that horrifying and devious warp entities cling to the arriving voidships, and that these malignant spirits seek to
travel to the planet surface. The veil between the Empyrean and reality
are thinnest on Harrow'e'en according to the citizens, so the Tithe Fleet
arrival is a time of great peril. The Adeptus Ministorum has of course
contemplated this interesting belief and decreed there to be no conflict with
the Imperial Faith. The priesthood of the planet support it fully.”

“The day preceding the docking of the first voidship is the
most active as the populace prepares for the arrival. On this day, most of the
citizens stay indoors, and those that venture out are likely to meet with a
raucous procession led by ‘Spirits of the Warp’. This parade is sponsored by
the Order of the Ossuary, a sanctioned mendicant society of relic venerators.
The most devout among them may be selected to personify a Spirit of the Warp, a
symbolic representation of the fears of the populace.”
“Children that are able to recite their hymns of protection
are allowed to wear bizarre and creative costumes. These wildly attired
rapscallions spend the day roaming the streets seeking citizens for the
procession to test. Anyone detained by the roaming children must stop and
recite the proper prayers of protection to the nearest Sister of the Order
Famulous. Woe to the unprepared citizen
who is surrounded by these enthusiastic imps and knows not their Harrow’e’en
prayers!”
