Filling the gaps before and after Nest of the Eldritch Eye, and Vecna: Eve of Ruin

Good evening.  I’m currently in Chapter 8 in Eve of Ruin with my current group.   I was thinking of running this campaign with a new group, but want to flesh it out for a full 1-20 campaign.   Which means I would need to fill the gaps from 1-2 leading into NotEE, and then from 4-10 leading into EoR.   Anyone have any suggestions on what I could use that would make sense?  Thanks in advance.

Greetings Treabor21,

I have had this conversation with a few of my players that want to play Eave of Ruin, but also want to try a full Level 1 to Level 20 campaign.

What I was thinking of doing was one of two routes, and then present the options to my players and let them decide:

Options for Levels 1 to 2:

1. Using information on the Forgotten Realms, do a Little Sandboxing, and let the Party find their footing. Let them all meet, and get to know each other, go on some small adventures around a town (quests are on a public board for individuals looking for help), etc.
   
   
2. Run an adventure out of one of the Anthology Books, like; The Sunless Citadel (Tales from the Yawning Portal), or Death at Sunset (Dragon Delves).

At Level 3 run Vecna Nest of the Eldritch Eye.

Options for Levels 4 to 10:

1. Run Planescape: Adventures in the Multiverse to take them from level 4 to 10.
   
   
2. Choose some Adventures from different Anthology Books and stitch them together, like;
   • Quests from the Infinite Staircase: When a Star Falls (4-5), Beyond the Crystal Cave (6), Pharaoh (7-8), The Lost Cavers of Tsojcanth (9-10).
   • Tales from the Yawning Portal: The Forge of Fury (4-5), Hidden Shrine of Tamoachan (5-7), White Plume Mountain (8), Dead in Thay (9-11).

At level 10 run Vecna: Eve of Ruin all the way to level 20.

Not sure if this helps at all, but I hope it gives some ideas :)

Cheers!
